JavaScript
13 Comments1 Solution740 ViewsLast Modified:
Let's say I am selling shirts and pants. There are multiple products. For each product, I have a dropdown select box containing different color options and textfield next to it which is to show the price associated for each color. I want the price shown in the text field changes as user chooses different color. I have array created under javascript in this format:
Array[]= Array (price,color_code,product)
color_code are W,B,Y,G etc  (W for white, B for black etc)

Currently I have following array created
<SCRIPT type="text/javascript" language="JavaScript 1.2">
var Xarray = new Array();
Xarray [0] = new Array('15, 'B', 'Shirt');
Xarray [1] = new Array('16, 'W', 'Shirt');
Xarray [2] = new Array('18, 'Y', 'Shirt');
Xarray [3] = new Array('12, 'G', 'Shirt');
Xarray [4] = new Array('11, 'B', 'Pant');
Xarray [5] = new Array('13, 'W', 'Pant');
Xarray [6] = new Array('12, 'Y', 'Pant');
Xarray [7] = new Array('18, 'G', 'Pant');
</SCRIPT>

And I have select box and textfield as follows.
<select name="product_type_color">
          <option value="W" selected>White</option>
          <option value="B">Black</option>
          <option value="Y">Yellow</option>
        </select>
<input type="text" name="poduct_id_price">

Could someone help me write a javascript that will autofill the price textfield as change in dropdown select is triggered? Both type of product (shirt or pant) and Color (W,B,G,  or Y) must match to get a correct price.
